Thought I would post up some dyno graphs of some friends trucks that were tuned by a local tuner here in Victoria.
The first is a 07 Silverado quad cab with a p1sc blower at 9psi everything else is bone stock.

The other is a 05 quad cab Silverado with a 220/220 cam and LT headers

Looking good!
Power is just right for that cammed truck.
Seems procharger isn't making power on the new trucks.
I think with the location of the filter on the 07 it brings a lot of hot air in off the motor affecting it.
If he would have done some supporting mods it would of helped alot. There was no place to hook up the dyno MAP sensor so I don't know if it really was making 9 psi.
But 250rwhp stock, 285rwhp with tune then 413 with p1sc (45% gain over a tuned truck or 65% over a stock truck) falls in line of about what a little P1sc will do.
He needs to upgrade his exhaust and to a D1SC.
Ya, same for a turbo, 10psi is about +-400whp, so I guess it's right on track.Quote:
